Question

Explain Bohr's model of an atom.​

Answer 1

Answer:

Bohr model of atom:

electrons revolving around the nucleus in fixed circular path called orbits or shells. each orbit is associated with definite energy and called energy level and is numbered as 1, 2, 3, 4 or k, l, m, n

electrons revolving around the same orbit will not lose or gain energy and are called stationary orbits.

due to the circular movement of electrons around the atom they acquire an angular momentum which is equal to the whole number multiple of h/2pi ie mvr = nh/2pi

when electron jump from one shell to another they should either loss or gain energy of definite frequency. that frequency = E2-E1/h

$\huge{ \mathfrak{ \underline{Bohr's \: Model \: Of \: An \: Atom }}}$

There were many scientists who were curious about knowing the structure of an atom.

Thomson, Rutherford showed their experimental evidences, but failed to know about the atomic structure.

Neil's Bohr finally succeeded.

• Who was Neil's Bohr?

Neil's Bohr was a professor of physics at Copenhagen University in 1916. He was born in Copenhagen onn7th of October 1885. He got a Nobel Prize for his work on the structure of an atom in 1922!

Coming to the topic, Bohr's Model Of An Atom :

• Only certain special orbits known as the discrete orbits of electrons, are allowed inside the atom.

• While revolving in the discrete orbits, electrons do not radiate energy.

• There orbits or shells were called energy levels.

• These orbits are represented by the letters K,L,M,N or by numbers 1,2,3 & 4.

• The protons having the positive charge are present in the nucleus. The electrons revolve around the nucleus.

An atom has 3 subatomic particles, which are the protons, electrons, and the neutrons. Neutrons are neutral in charge.

Let's have a look at what protons and electrons actually are.

Protons :

Protons : Protons are positively charged particles and are denoted by p+. Their charge is +1. The mass of a proton is taken as 1 unit.

Electrons :

Protons : Protons are positively charged particles and are denoted by p+. Their charge is +1. The mass of a proton is taken as 1 unit. Electrons :Electrons are negatively charged particles and are denoted by e-. Their charge is negligible, hence it is taken as -1.
